be used that maintain the junction temperature as close to the ambient temperature as possible. All characteristics are measured with a 0.1-µF
capacitor across the input and a 1-µF capacitor across the output.
NOTE 3: Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
